yeah I guess that a couple seconds is too long ... the time it takes to nav back or hover over a button on Kinect is too long for me personally, but guess it has to be a least a second as to not keep entering commands in error when just passing over UI.
I also use mouse buttons to nav back/fwd, and is quick as you'd like.
....I'm just speculating at how this type of tech 'might' come to be used in the future.
It might flop and not go anywhere, I guess it depends on how smart it is. I can only imagine it will work something like how Kinect does.
Eye detection might not offer any improvement over mouse control, but it might, depending how it pans out.
Certainly for certain users who might have disability and can't use hands very well, this could be good.
Fighter pilots, who already use eye detection to control their missiles [in the Harrier Jumpjet planes I think]
Truth is, I dunno ... just read about it in that article, got a bit wowed by it but will have to wait to see it myself, it might be terrible, might work pretty nice
Columbo would probably not find this too useful, agreed.
